In a superb display of skill, Shohei Ohtani's performance was the highlight of Japan's first game in the 2026 World Baseball Classic, held at the Tokyo Dome against Taiwan. Starting as the designated hitter, Ohtani ignited the crowd by hitting a double on the first pitch he faced and later stunned fans by hitting a grand slam off Taiwan's starting pitcher, Zheng Haojun, during a bases-loaded situation. Japan scored an unprecedented 10 runs in the second inning, with Ohtani contributing five RBIs, setting a new WBC record for most runs scored in a single inning and five RBIs in a single game.

Ohtani's home run was accompanied by a unique 'tea ceremony' gesture as he rounded the bases, symbolizing the blending of traditional Japanese culture with baseball. This ceremonial act, planned by teammate Koki Kitayama, aimed to encourage younger players by creating a lighter atmosphere and emphasizing the spirit of sportsmanship. Japan had previously made headlines in the 2023 tournament with a quirky 'pepper grinder' celebration, showcasing the team's playful but fierce competitive spirit.

With Japan's dominating performance, including a total of 13 hits and a no-hitter pitched by Yoshinobu Yamamoto, the game concluded after seven innings due to the mercy rule, resulting in a crushing 13-0 victory. Such strong beginnings not only set a positive tone for the team in this championship but also reaffirm Japan's status as a formidable contender in international baseball.
